machines (B1, C1). I used the B1 for a while to do some debugging. The C1
did sit there idle.

the mouse fine but touch interaction does not work. This machine has just
been started, no further interaction besides some s/r cycles.

Paul found in the logs that it failed to detect its touchscreen when it
booted.

Trying to reload the module with "modprobe -r zforce; modprobe zforce" did
not work. Reloading with "modprobe -r zforce; modprobe zforce forceload=1"
did bring it back and I could use touch interaction (the cursor hiding did
not work though).
zforce firmware version "dmesg | grep zforce" is 0.0.0.9.
